7-year-old writes goodbye message to parents during bomb threat

One 7-year-old's touching message to her parents has taken Facebook by storm.

Shelley Harrison Reed posted a photo of her daughter Vanessa with the words 'Love Mom and Dad' written on her arm in purple marker.

Reed already knew from her 10-year-old son that their Delaware school had been under lockdown during a portion of the day because of a bomb threat.

When Reed noticed the strange message on Vanessa's arm, she asked her daughter what it meant.

The second-grader explained she wrote it to let her parents know she loved them in case she was killed.

Reed wrote they both started to cry as she watched a piece of her daughter's innocence "get stolen away."

No one in the school was hurt.
